Quick LaTeX Tutorial

[Dave]

Can you give me an example?

Can you give me an example?

 

Yea shure

 

[math]

\begin{array}{c|c}

Name & Age\\

Row & 2

\end{array}

[/math]

 

Cheers,

[Dave]

I'll sort that out; I think I probably know what the problem is.

OK, thanks Dave

Very interesting

[math]A_\phi=\tfrac{2}{3}r^{-2} - \tfrac{1}{3}(2r^{-2}+2r^{-1}+1)e^{-r} - \tfrac{r}{3}(\int{r^{-1}e^{-r}}-\gamma)[/math] BABE, THANKS, NOW I'M COOOOOL WITH MY ROCK'N'ROLL ELECTRONS.

[Cap'n Refsmmat]

That's [math]A_\phi= \tfrac{2}{3}[/math]

 

And you can hit Preview Post to see how it will turn out.

[math]x^2_1[/math]

[hotcommodity]

[math]\sum_{n=1}^{\infty}\frac{(-1)^nn^3}{3^n}[/math]

 

[math]\left|\frac{a_{n+1}}{a_n}\right|=\frac{(n+1)^3}{3^{n+1}}\frac{3^n}{n^3}=\frac{1}{3}{\frac{{n+1}^3}{{n}^3}}=\frac{1}{3}(1+\frac{n}n\right)^3[/math]

 

How do I fix the abs. value and get ((n+1)/n)^3 instead of (n+1^3)/n?`

[D H]

How do I fix the abs. value?

 

Use \left and \right:

 

[math]\left|\frac{a_{n+1}}{a_n}\right|[/math]

 

How do I get ((n+1)/n)^3 instead of (n+1^3)/n?

 

Same thing again, only use parens instead of the vertical bar as arguments of left and right:

 

[math]\left(\frac{n+1}n\right)^3[/math]

[hotcommodity]

Thanks D H

[math]y = x^2 - 4x + 3[/math]

 

[math](y + \Delta y) = (x + \Delta x)^2 - 4(x + \Delta x) + 3[/math]

 

[math]y + \Delta y = x^2 + 2x \Delta x + (\Delta x)^2 - 4x - 4\Delta x + 3[/math]

 

[math]y + \Delta y = (x^2 - 4x + 3) + 2x\Delta x - 4\Delta x + (\Delta x)^2[/math]

 

[math]\Delta y = 2x \Delta x - 4\Delta x + (\Delta x)^2[/math]

 

[math]\frac {\Delta y}{\Delta x} = 2x - 4 + \Delta x[/math]

 

[math]\frac {dy}{dx} = 2x - 4[/math]

 

Just practicing differentiation...

 

[math]X^2 = \sum_{i=1}^{n}\frac {(O_i - E_i)^2}{E_i}[/math]

 

a simple [math]X^2[/math] test equation.

 

Just some of my current course content, need to get to grips with Latex, before I start asking any math related questions.

[solo]

[math]\left[\left(\frac{\hbar c}{e^2}\right)^3 \left(\frac{\hbar c}{G^3}\right)^3 \left(\frac{\hbar re}{G^3}\right)^{1.111111....}\right] = \left(\pi\right)^3[/math]

[no genius]

[math]\sum _{i=1}^{\infty }A_{{i}}=5[/math]

 

nice. i <3 maple's latex converter.

[w=f[z]]

[math]A^\mu _{\ ; \nu}=\frac{\partial A^\mu}{\partial x^\nu}+\Gamma^\mu_{\nu \lambda}A^\lambda \ \ \ A _{\mu ; \nu}=\frac{\partial A_\mu}{\partial x^\nu}-\Gamma^\lambda_{\mu \nu}A_\lambda[/math]

 

Just goofin' around....

 

Very glad this forum has LaTeX.

[Tartaglia]

Just testing

\frac{\partial F}{\partial X}

[Norman Albers]

I'd like to know how to lay out matrices (4x4). . . . .OK I see how to get started on p. 2; sorry.

[Norman Albers]

Vector cross-product?

[timo]

Vector cross-product?

What are you asking? For a symbol that can be used for the cross-product? Try "\times".

[Norman Albers]

[math]r\times A [/math]. Thanks, mate! Here is a compatible reference I have downloaded: http://amath.colorado.edu/documentation/LaTeX/Symbols.pdf

[no genius]

[math] \left( \Psi \left( x+1 \right) -\Psi \left( x-1 \right) \right) {x \choose 2}[/math]

[Norman Albers]

Limits of evaluation: [math] I®\vline _1^R [/math]. Larger, [math] \frac{F}{G}|_1^R[/math]. Nope, how do we do "evaluated at"?

[the tree]

[math]\forall n \in \mathbb{N} \backslash \left \{ 1 \right \} \exists p,q \in \mathbb{P} : 2n=p+q[/math]

 

A random question, my course teaches use of LaTeX, how common is that? Have other people mostly had to teach themselves?

[math]\forall n \in \mathbb{N} \backslash \left \{ 1 \right \} \exists p,q \in \mathbb{P} : 2n=p+q[/math]

I learned it here.

[PhDP]

I learned it here.

 

You mean, writing equations with LaTeX ? Or writing documents with LaTeX ?

 

I learned to write documents with LaTeX by myself, I'm not an expert but I'm good enough to write articles with it, it's really much better than Microsoft Word. I use MiKTeX + TeXnicCenter.
